[...] In 1 Corinthians Ch 7:12-15 Jesus gives permission for divorce when two become one.. but one does not and refuses to believe. [...]
1 Corinthians 7:12-15 sounds like Paul is making a distinction between his advice and God's. His advice also does not allow for remarriage after divorce. Matthew 19:8-9 shows that Jesus believes if we divorce our spouse and marry another we are committing adultery. The only exception to the rule, in my understanding of the Jewish marriage process, was that we
could (not
should) divorce our wife before consummation if we found her to be unfaithful/not a virgin. I think this is what Jesus is talking about. If you believe you have sinned by becoming unequally yoked with an unbeliever, then what good will the sin of divorce do for you? I believe your situation is very serious, but you are not alone.
Also, when the Bible tells married women to win over their husbands through their 'conversation' it should be better translated as 'win them over through the way they live.' It doesn't mean to talk them into repentance. As we can see from real life that rarely works. It just means to win by example. Be a Christian that God would be proud of. Try to win him over through love, open worship of God, kind stubbornness in your faith and humility. And also keep in mind that Paul here is implying that believing wives
should remain in a relationship with their unbelieving husband. Presumably as long as possible...
1 Peter 3:1-2 "In the same way, wives, submit to your husbands; so that even if some of them do not believe the Word, they will be won over by your conduct, without your saying anything, as they see your respectful and pure behavior." - Complete Jewish Bible (CJB) Young's
Literal Translation also agrees for the most part with this translation.
Concerning how you should raise your children, I believe you should communicate your concerns to him in a sincere manner. Let him know that he has his beliefs but that you also have yours and would like him to consider yours. Let him know that if he wants to raise his children in a pagan tradition then you would also want to raise your children in a Christian tradition and would like for them to choose for themselves their own religion.
I have little experience in this case, so my advice is meager. I hope it helps, though. Take care, WhiteRose.
